O objetivo deste trabalho foi determinar o método de coleta de fezes mais adequado para camarões marinhos (Litopenaeus vannamei) na determinação do coeficiente de digestibilidade aparente da proteína bruta e da matéria seca de dietas comerciais, e avaliar o efeito da suplementação de Lactobacillus plantarum na dieta sobre o coeficiente de digestibilidade aparente da proteína, da energia e da matéria seca. Foram testados três sistemas de coletas de fezes: decantação, sifonamento e dissecação dos animais. A coleta por decantação foi o sistema mais adequado para a determinação in vivo dos coeficientes de digestibilidade aparente da proteína bruta e da matéria seca das dietas, por apresentar baixo grau de lixiviação das fezes e por ser de fácil execução. Nos...

The objective of this work was to isolate strains of lactic acid bacteria with probiotic potential from the digestive tract of marine shrimp (Litopenaeus vannamei), and to carry out in vitro selection based on multiple characters. The ideotype (ideal proposed strain) was defined by the highest averages for the traits maximum growth velocity, final count of viable cells, and inhibition halo against nine freshwater and marine pathogens, and by the lowest averages for the traits duplication time and resistance of strains to NaCl (1.5 and 3%), pH (6, 8, and 9), and biliary salts (5%). Mahalanobis distance (D²) was estimated among the evaluated strains, and the best ones were those with the shortest distances to the ideotype. Ten bacterial strains were isolated...

Lactic acid bacteria used as preservative in fresh feed for marine shrimp maturation
Provedor de dados: Pesquisa Agropecuária Brasileira

Abstract The objective of this work was to evaluate the effect of Lactobacillus plantarum on the preservation of fresh mussels and its effect on the attractiveness, consumption, and midgut bacterial microbiota of Pacific white shrimp broodstock. The experiment evaluated mussels stored with L. plantarum at 4ºC. The controls were: mussels stored at -18ºC without L. plantarum; mussels stored at -18ºC with L. plantarum; and mussels stored at 4ºC without L. plantarum. Microbiological analyses on mussels were performed on days 1, 7, 15, 30, 45, and 60 after processing. Additionally, mussels preserved with L. plantarum and stored at 4ºC, and mussels stored at -18ºC without L. plantarum were evaluated after 15 days for attractiveness, consumption, and midgut...

Replacement of fishmeal for soy protein concentrate in diets for juvenile Litopenaeus vannamei in biofloc-based rearing system
Provedor de dados: Revista Brasileira de Zootecnia
Autores: Jatobá,Adolfo; Vieira,Felipe do Nascimento; Silva,Bruno Corrêa da; Soares,Mariana; Mouriño,José Luiz Pedreira; Seiffert,Walter Quadros.
ABSTRACT This study aimed to assess the final body weight, weekly weight gain, yield, apparent feed efficiency, protein efficiency ratio, and feed intake of the Pacific white shrimp (Litopenaeus vannamei) fed four diets containing different levels of soy protein concentrate (SPC) as a replacement for fishmeal, reared in a super-intensive biofloc system. Diets consisted of replacing 209 g kg-1 fishmeal at 0, 33, 66, and 100% SPC. Shrimp were raised in a biofloc system using twelve experimental units stocked with 250 shrimp m-3 under constant aeration (O2&gt;5mg L-1) and temperature (29±0.5 °C). No significant differences among treatments were observed based on water quality parameters. Shrimp fed diets with 0 and 33% substitution exhibited the highest...

Hydrogen peroxide and chlorine dioxide against parasite Ichthyophthirius multifiliis (Protozoa, Ciliophora) in jundiá fingerlings
Provedor de dados: Ciência Rural
Autores: Marchiori,Natalia da Costa; Silva,Fabiano Muller; Martins,Maurício Laterça; Amaral Junior,Hilton; Silva,Bruno Corrêa da.
ABSTRACT: Ichthyophthiriasis is a worldwide fish disease with great financial impact on freshwater fish farming due to its associated high mortality rates. Current study assesses the parasiticidal capacity of hydrogen peroxide (H2O2) and chlorine dioxide (ClO2) against the causative agent, Ichthyophthirius multifiliis, in jundiá. Median lethal concentration (LC50, 96h) of each chemical agent was established, as well as the minimum inhibitory concentration of hydrogen peroxide for the parasite´s infectious larval phase (theront). Products were tested asynchronously in parasitized fingerlings for short and long baths at the following concentrations and exposure times: 1. Hydrogen peroxide: (T1) continuous bath - 30ppm and (T2) 50ppm; (T3) short bath -...
